Additional Details

The CD1376C typically comes in a surface-mount package, allowing for automated assembly on PCBs. Key specifications include its impedance at specific frequencies (e.g., 90 ohms at 100 MHz), rated current, DC resistance, and voltage rating. Understanding these specifications is crucial for selecting the appropriate choke for a given application. The specific characteristics of the Murata CD1376C make it well-suited for applications requiring robust common mode noise suppression without compromising signal integrity.

Careful consideration of the application's frequency range and noise characteristics is important when selecting a common mode choke. The CD1376C’s performance characteristics should be reviewed against these requirements to ensure optimal noise suppression. Properly implemented, this choke can significantly enhance the performance and reliability of electronic systems.
